Acknowledgements The Parks and Wildlife Service at the Department of Biodiversity, Conservation and Attractions (DBCA; the department) would like to thank the many people who have been involved in the development of the Toolibin Lake Recovery Plan 2015–35. In particular, valuable input has been provided by past and present members of the Toolibin Lake recovery team and technical advisory group, the department’s planning support staff (Danielle England, Jennifer Higbid, Maria Lee, Loretta Lewis, Ray McKnight, Michael Smith, Ellen Trimming and Ken Wallace) and a number of other individuals (Brett Beecham, Lindsay Bourke, Paul Drake, Greg Durell, Peter Lacey and Peter White); and Geographic Information Services Branch. We gratefully acknowledge the support and the research‐driven methodological innovation contributed by the School of Computer Science at the University of Nottingham, led by Dr Christian Wagner and funded by the UK EPSRC (EP/K012479/1) and NERC (NE/M008401/1). The research conducted and its outputs have been instrumental in both informing key aspects of this management plan and advancing the methodological research underpinning it. The department would especially like to thank Dr Jasmine Rutherford, senior hydrologist for her involvement in development of the recovery plan. The advice and technical input of Dr Ryan Vogwill into the plan and the planning process is also greatly appreciated. Accessibility This document is available in alternative formats on request.
